Sehr geehrtes Expertenteam, Rauchen lässt Ihre Haut altern, das steht auf jeder Zigarettenschachtel. Wenn die Haut schneller altert, wird die Haaralterung logischerweise auch vorangetrieben. Wenn das Haar schneller altert, fällt es Haar verfrüht aus. Kann man das so sagen? viele Grüße |

Sehr geehrter Lutz, anbei ein wenig Literatur zu dem Thema. Manche Autoren sehen einen Zusammenhang zwischen Rauchen und Haarverlust. Unklar ist der genaue Mechanismus - vermutet wird der oxidative Stress ausgelöst durch das Rauchen. Ein schädigender Einfluss des Zigarettenrauchens auf die Entstehung einer androgenetischen Alopezie ist nicht nachgewiesen. Förderlich für die Gesundheit ist Rauchen in jedem Fall nicht! Freiman A, Bird G, Metelitsa AI, Barankin B, Lauzon GJ. Cutaneous effects of smoking. J Cutan Med Surg. 2004 Nov-Dec;8(6):415-23. BACKGROUND: Cigarette smoking is the single biggest preventable cause of death and disability in developed countries and is a significant public health concern. While known to be strongly associated with a number of cardiovascular and pulmonary diseases and cancers, smoking also leads to a variety of cutaneous manifestations. OBJECTIVE: This article reviews the effects of cigarette smoking on the skin and its appendages. METHODS: A literature review was based on a MEDLINE search (1966-2004) for English-language articles using the MeSH terms cutaneous, dermatology, tobacco, skin, and smoking. An additional search was subsequently undertaken for articles related to smoking and associated mucocutanous diseases, with the focus on pathogenesis and epidemiologic data. Articles presenting the highest level of evidence and latest reports were preferentially selected. RESULTS: Smoking is strongly associated with numerous dermatologic conditions including poor wound healing, wrinkling and premature skin aging, squamous cell carcinoma, psoriasis, hidradenitis suppurativa, hair loss, oral cancers, and other oral conditions. In addition, it has an impact on the skin lesions observed in diabetes, lupus, and AIDS. The evidence linking smoking and melanoma, eczema, and acne is inconclusive. Anecdotal data exist on the possible protective effects of smoking in oral/genital aphthosis of Behçet's disease, herpes labialis, pyoderma gangrenosum, acral melanoma, and Kaposi's sarcoma in AIDS patients. CONCLUSIONS: An appreciation of the adverse cutaneous consequences of smoking is important. Dermatologists can play an integral role in promoting smoking cessation by providing expert opinion and educating the public on the deleterious effects of smoking on the skin. Severi G, Sinclair R, Hopper JL, English DR, McCredie MR, Boyle P, Giles GG. Androgenetic alopecia in men aged 40-69 years: prevalence and risk factors. Br J Dermatol. 2003 Dec;149(6):1207-13. BACKGROUND: The epidemiology of androgenetic alopecia (AGA) is not fully understood. Although a strong genetic basis has long been identified, little is known of its non-genetic causes. OBJECTIVES: To estimate the prevalence of and to determine risk factors for AGA in men aged 40-69 years in Australia. METHODS: Men (n = 1390) were recruited at random from the electoral rolls to serve as controls in a population-based case-control study of prostate cancer. All were interviewed in person and direct observations of AGA were made. Men were grouped into the following categories; no AGA, frontal AGA, vertex AGA and full AGA (frontal and vertex AGA). Epidemiological data collected from these men were used for an analysis of risk factors for each AGA category using unconditional logistic regression with AGA category as the response variable adjusting for age, education and country of birth. RESULTS: The prevalence of vertex and full AGA increased with age from 31% (age 40-55 years) to 53% (age 65-69 years). Conversely, the proportion of men with only frontal AGA was very similar across all age groups (31-33%). No associations were found between pubertal growth spurt or acne, reports of adult body size at time of interview, urinary symptom score, marital status, or current smoking status or duration of smoking and the risk of any form of AGA. The consumption of alcohol was associated with a significant increase in risk of frontal and vertex AGA but not full AGA. Men with vertex AGA had fewer female sexual partners but average ejaculatory frequency did not differ between men in different AGA categories. Reported weight and lean body mass at reaching maturity at about 21 years of age were negatively associated with vertex balding (P for trend < 0.05) but not with frontal AGA or full AGA. CONCLUSIONS: Evidence for environmental influences on AGA remains very slight. Our study failed to confirm previously reported or hypothesized associations with smoking and benign prostatic hypertrophy. The associations that we found with alcohol consumption and with lean body mass at age 21 years would be worthy of further research if they were able to be replicated in other studies. | |
